OP27
GENERAL DESCRIPTION
(Continued from Page 1)
PSRR and CMRR exceed 120 dB. These characteristics, coupled
with long-term drift of 0.2 μV/month, allow the circuit designer
to achieve performance levels previously attained only by
discrete designs.
Low cost, high volume production of OP27 is achieved by
using an on-chip Zener zap-trimming network. This reliable
and stable offset trimming scheme has proven its effectiveness
over many years of production history.
The OP27 provides excellent performance in low noise,
high accuracy amplification of low level signals. Applications
include stable integrators, precision summing amplifiers,
precision voltage threshold detectors, comparators, and
professional audio circuits such as tape heads and micro-
phone preamplifiers.
The OP27 is a direct replacement for
and
amplifiers;
types can be directly replaced by removing
